In the printing industry, UV technology, as an advanced post press processing technique, is gradually gaining popularity among more and more printing companies and customers. UV technology adds endless charm to printed materials with its unique glossiness, wear resistance, and environmental friendliness.
Overview of UV Process
UV technology, also known as ultraviolet curing technology, is a technique that uses ultraviolet radiation to instantly cure ink or varnish. In the printing industry, UV technology is mainly used in post press processing, such as UV polishing, UV coating, etc. The ink or varnish used in UV technology contains photosensitizers. Under UV irradiation, the photosensitizers undergo chemical reactions, causing the ink or varnish to quickly solidify into a film.
Characteristics of UV technology
High glossiness: The ink or glossy layer cured by UV technology has extremely high glossiness, which can significantly improve the visual effect of printed materials.
Good wear resistance: UV cured film has extremely strong wear resistance, which can effectively prevent the surface of printed materials from being scratched or worn.
Environmentally friendly: UV technology does not produce volatile organic compounds (VOCs) during the curing process, which is pollution-free and meets environmental requirements.
Fast curing speed: UV technology has a fast curing speed, which can complete the curing process in a short time and improve production efficiency.
Strong adaptability: UV technology is suitable for various printing materials and printing methods, and can meet the needs of different customers.
Application scenarios of UV technology
UV Polishing: After applying UV varnish on the surface of printed materials, it is cured into a film by UV irradiation, forming a high brightness glossy layer. UV polishing is widely used in high-end picture books, packaging decoration, advertising and promotional materials, and other fields.
UV coating: Covering the surface of a printed product with a UV cured film, and tightly adhering it to the surface of the printed product through UV irradiation. UV coating can significantly improve the wear resistance and waterproofing of printed materials, and is widely used in fields such as book covers and extremely colorful packaging boxes.
UV local polishing: Apply UV varnish to specific areas on the surface of printed materials and cure them to form a locally high brightness glossy effect. UV local polishing can highlight the key information of printed materials and enhance visual effects.
Precautions for UV technology
Choose the appropriate UV ink or varnish: Select the appropriate UV ink or varnish based on the needs of the printed material and the characteristics of the printing material.
Adjust printing equipment parameters: Ensure that the printing equipment parameters are set reasonably to ensure printing quality and efficiency.
Control curing time: Control the curing time based on the characteristics of UV ink or varnish and the thickness of the printed material to avoid insufficient or excessive curing.
Pay attention to safe operation: During the operation, pay attention to protecting the eyes and skin from UV radiation, and avoid UV ink or varnish from contacting the skin and eyes.
